My best (or worse) was when I was young and stupid.....not that the second one there has changed much
Met up with a bunch of squaddies in Germany drinking their lager and chased up by shorts (so I'm told anyway).
The next day we were driving up to Hanburg (me in the passenger seat - obviously) deep breathing as you do when feeling that sh1tty, asked to pull over 'cos really wasn't feeling too good - collapsed out of the car in the foetal position with wrists, elbows etc all curling up tight - Friends running around without heads etc, but somebody sensible called an ambulance. When they eventually arrived - they stuck a paper bag over my head - not because I'm ugly - but to stop me hyperventilating - off to hospital, drip etc
strange I've never really done that again
